Background/Aims: Central auditory function can be studied to monitor the progression of mild cognitive impairment to dementia. Our aim was to address this issue in a prospective longitudinal setting. Methods: Tests of central hearing function were performed on 70 subjects with either Alzheimer's disease (AD) or mild cognitive impairment, and in controls with subjective memory complaints but normal cognition. The time span until follow-up was 1.5 years. Results: The dichotic digit free recall test showed a significant decline in the AD group compared with the controls (left ear). Conclusion: The short time span was long enough to disclose a central auditory processing decline in AD.
